Disorientation caused crash

The March 10 crash of Louisiana National Guard UH-60 helicopters in the water near Navarre, Fla., was due to the "spatial disorientation" of the pilot. That happens when a person's sense of place, where he or she is relative to the surroundings, is lost due to fog or other conditions. The helicopter crash killed seven Marines and four National Guardsmen. Another helicopter that was training at the time returned to Eglin Air Force Base because of the conditions.
